| 3 | Mycoplasma infections and different human carcinomas显示文摘AIM To explore relationships between human carcinomas and mycoplasma infection.METHODS Monoclonal antibody PD4, which specifically recognizes a distinct protein from mycoplasma hyorhinis, was used to detect mycoplasma infection in different paraffinembedded carcinoma tissues with immunohistochemistry. PCR was applied to amplify the mycoplasma DNA from the positive samples for confirming immunohistochemistry.RESULTS Fifty of 90 cases (56%) of gastric carcinoma were positive for mycoplasma hyorhinis. In other gastric diseases, the mycoplasma infection ratio was 28% (18/49) in chronic superficial gastritis, 30% (14/ 46) in gastric ulcer and 37% (18/ 49) in intestinal metaplasia. The difference is significant with gastric cancer (X2=12.06, P<0.05). In colon carcinoma, the mycoplasma infection ratio was 55.1% (32/58), but it was 20.9% (10/49) in adenomarous polyp (X2=13.46, P<0.005).Gastric and colon cancers with high differentiation had a higher mycoplasma infection ratio than those with low differentiation (P< 0.05). Mycoplasma infection in esophageal cancer, lung cancer, breast cancer and glioma was 50.9% (27/53), 52.6% (31/ 59), 39.7%(25/63) and 41% (38/91), respectively. The mycoplasma DNA was successfully amplified with the DNA extracted from the cancer tissues that were positive for mycoplasma infection (detected with antibody PD4).CONCLUSION There was high correlation between mycoplasma infection and different cancers, which suggests the possibility of an association between the two. The mechanism involved in oncogenesis by mycoplasma remains unknown. | Su Huang Ji You Li Jan Wu Lin Meng Cheng Chao Shou Beijing Institute for Cancer Research, Peking University School of Oncology, Beijing 100034.

| 4 | Clostridium difficile infections in China显示文摘Clostridium difficile (C. difficile) infection has become one of the major hospital-associated infections in West-ern countries in the last two decades. However, there is limited information on the status of C. difficile infection inChinese healthcare settings. Given the large and increasing elderly population and the well-recognized problem ofover-prescribing of broad spectrum antibiotics in China, it is critical to understand the epidemiology and potentialrisk factors that may contribute to C. difficile infection in China. A literature review of available published studies,including those in Chinese language-based journals, was conducted. A review of the currently available literaturesuggested the presence of C. difficile infections in China, but also suggested that these infections were not particu-larly endemic. This finding should lead to better designed and greatly expanded studies to provide a more reliableepidemiologically-based conclusion on the actual status of C. difficile infection in China, including the identifica-tion of any associated risk factors. Such information is ultimately valuable to develop appropriate strategies to pre-vent C. difficile infection and the vast negative impact of such infections in China and other developing countries. | Ke Jin a,b,c,Shixia Wang c,d,Zuhu Huang a,b,c,Shan Lu b,c,daDepartment of Infectious Diseases,bJiangsu Province Key Laboratory in Infectious Diseases,cChina-US Vaccine ResearchCenter,the First Affiliated Hospital of Nanjing Medical University,Nanjing,Jiangsu 210029,China d Department of Medicine,University of Massachusetts Medical School,Worcester,MA 01655,USA. | 2010 | The Journal of Biomedical Research2010，24，6： | 14 |
| 5 | Motion behavior of particles in air-solid magnetically stabilized fluidized beds for separation显示文摘In order to study the settling mechanism of particles in an air-solid magnetically stabilized fluidized bed(MSFB) for separation,we carried out free settling and quasi-zero settling tests on the tracing particles.The results show that the main resistance forces as the tracing particles settled in an air-solid MSFB were motion resistance force and yield force.The motion resistance and yield forces greatly hindered the free settling of the particles by greatly decreasing the acceleration for settling process of the particles.The acceleration decreased from 3022.62 cm/s 2 to zero in 0.1 s,and in the end,the particles stopped in the air-solid MSFB.The yield force on particles increased with increasing the magnetic field intensity,resulting in decrease of the quasi-zero settling displacement.However,the yield force on particles decreased with increasing the fluidized air velocity,leading to increase of the quasi-zero settling displacement.When the structure and operating parameters of the air-solid MSFB were set up,the yield stress on particles stopped in an air-solid MSFB was a function of diameter and density of particles.The settling displacements of equal diameter particles increased with increasing their densities,and the settling displacements of equal density particles increased with increasing their diameters. | Song Shulei a,,Zhao Yuemin a,Luo Zhenfu a,Tang Ligang b a School of Chemical Engineering and Technology,China University of Mining & Technology,Xuzhou 221116,China b Coal Mining and Designing Department,Tiandi Science & Technology Company Co.Ltd.,Beijing 100013,China | 2012 | International Journal of Mining Science and Technology2012，22，5： | 13 |

| 8 | Effects of disinhibition on spatiotemporal pattern of neuronal first recruitment in neuronal networks显示文摘The propagation of neuronal activities is a key feature to understanding information processing in networks. The analysis based on first-spikes of bursts in turn plays an important role in the research of neuronal activity propagation. Our focus here is to investigate how spatiotemporal patterns of neuronal first-spikes are affected by disinhibition. Multi-electrode arrays were used to record stimulation-evoked bursts of multiple neurons in randomly cultured neuronal networks. Both the precise timing of and the rank relationships between first-spikes were analyzed. Compared with evoked bursts in the network's native state, the precise first-spike latencies in its dis-inhibited state are more consistent and the propagation of its bursting activities is much faster. Additional points of interest are that disinhibited neuronal networks can be evoked to generate stable and distinguishable neuronal first recruitment spatiotemporal patterns specific to the stimulation site, and that the disinhibition may cause the original spatiotemporal patterns to change in a heterogeneous manner with regards to different propagation pathways. | Liangbin Pana,b,c,1, Xindong Songa,b,c,1, Guangxin Xiang a,b,c, Jing Zhua,b,c, Jing Cheng a,b,c,d,a Medical Systems Biology Research Center, Tsinghua University School of Medicine, Beijing 100084, China b Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing 100084, China c National Engineering Research Center for Beijing Biochip Technology, 18 Life Science Parkway, Beijing 102206, China d State Key Laboratory of Biomembrane and Membrane Biotechnology, Tsinghua University, Beijing 100084, China | 2009 | Progress in Natural Science:Materials International2009，19，5： | 6 |
| 9 | Copper Adsorption on Olivine显示文摘Copper adsorption on olivine supplied by the A/S Olivine Production Plant at Aheim in western Norway was studied. The factors were evaluated which affect the uptake of copper. It is shown that the equilibrium pH of aqueous solution has the greatest influence on copper adsorption thanks to the competitive adsorption between proton and copper ions, and the adsorption of copper to olivine increases rapidly with pH increasing from 4 to 6. Moreover, initial copper concentration and olivine dose possess significant effect on copper adsorption, for the adsorption rate of copper increases with olivine dose increasing or initial copper concentration decreasing at the same pH. In addition, the ionic strength effect on the adsorption was also investigated, but it owns little effect on the adsorption process of copper due to the formation of inner sphere adsorption of copper on olivine. The experimental data show that olivine has a high acid buffer capacity and is an effective adsorbent for copper. | Lei Shao, Rolf A. Kleiv, Kunt L.
